tapping reaming systems why use a holder with radial float a holder that provides radial float should be selected for tapping or reaming applications where the hole that is to be tapped or reamed does not lie exactly on the machine spindle centerline typical examples of this may include the following types of equipment or operations · transfer line type equipment · dial type machines · reaming through bushing plates that are not aligned with the spindle s centerline · tapping machines that only tap a hole that is prepared somewhere else · tapping castings that have as cast holes and are not qualified by additional drilling on the same machine where tapping takes place why use a length compensating tap holder with radial float the lcth tap holder provides both radial float and length compensation for tapping operations it has the ability to float parallel off the machine spindle s centerline to the center of the hole to be tapped it also provides compensation tension and compression for spindle speeds and feed rates not matched to the pitch of the tap you are using the two features perform separate and distinct functions 1 radial float is desired when the hole you are trying to tap does not fall on the same centerline as the spindle this happens when transfer type machinery produces a hole at one station and then another station does the tapping operation some misalignment of the holes to be tapped can occur when the pallet fixture moves from the drilling station to the tapping station the floating holder compensates for the misalignment another example is however the misalignment occurs it must be compensated when tapped holes are made in cast parts where the holes are not finished machined in the same fixturing as where for before tapping or reaming to provide optimum results the holes are to be tapped this is sometimes referred to in tapping a holder that provides radial float allows the as tapping as cast holes for a high quality thread to be tap to find the center of the prepared hole and produce a produced the tap must find the center of the hole and then higher quality thread and better tap life no binding to the tap without any angularity or binding of the tap floating tap or angularity of the tapped hole to the spindle centerholders accommodate the misalignment tap life will be line is introduced by the tapping operation if the holder improved as well as a higher quality thread being procompensates for the misalignment duced 2 length compensation in the holder is the ability to in reaming the same things are true holes are someshorten or lengthen itself during the tapping cycle this times guided by bushing plates that are not in alignment allows the tap to feed at the proper pitch or its own pitch with the spindle s centerline and would cause binding or without any pushing or pulling forces on the tap pushing rubbing of the reamer going through the bushing the or pulling compression or tension actions will result in floating holder compensates for this the flank angles of the thread to be shaved and distorted on applications where there is no bushing plate used the this is a common source of oversized tapped holes or holes where there is crest damage to the thread form holder must allow the reamer to find the center of the hold or bell mouthing which is an imperfection to the di some sources of the mismatch of feeds and speeds may ameter at the entrance of the reamed hole can occur the include worn components on the machine or the inability to accurately control the feed and speed of the spindle to the reamer without a radial floating holder has to engage a sufficient amount of the reamer into the hole before it stabi pitch of the tap 3 compression is necessary when using a torque control lizes in cut during this time it can produce an oversized type of tap adapter this is a tap adapter that has a clutch hole at the entrance or bell mouthing inside it when a torque value is reached during tapping the clutch disengages from driving the tap and the tap either tapping or reaming works best when the cutting stops rotating the torque value is usually set at a prestool is not forced in any direction but allowed to cut freely sure just before the tap breaks the clutch re-engages on on it s own reverse of the spindle and backs the tap out of the hole if the clutch disengages during the forward tapping operation the holder must have the ability to compress on itself to compensate for the still advancing spindle not having this feature will result in a crash.

floating holders the result of continuous improvement taking the best of all worlds and making a superior product david smith chief operating officer the fith -ii radial floating holder employs a 6 ball differential drive system which provides a true round float with no cornering effect this drive allows for reduced mechanism diameter and increased radial torque by adding chip shields coolant thru coolant flow capabilities and adjustable centering pressure we have produced the most advanced floating holder the market has seen to date 1 1 high pressure coolant thru floating mechanism is designed to float freely with coolant pressures as high as 1000 psi 2 2 adjustable coolant flow control the flow control screw is adjustable to allow even volume of coolant to match the coolant hole in the cutting tool this reduces back pressure and allows the floating holder to work properly under any coolant flow 3 3 4 reduced diameter mechanism redesigned to work with close center cluster spindles or tight work areas 5 4 differential drive mechanism the 6 ball differential drive is designed to provide smooth radial float and eliminate the cornering that most mechanisms create from their drive pin designs fith-ii is the best holder for fine reaming and honing on the market today 6 7 5 adjustable centering pressure provides adjustment to the sensitivity of the float the option is primarily used on small taps fine reaming or honing 6 chip shield keeps coolant and chips from entering the front of the mechanism 7 6 ball drive coupling t.m smith developed the 6 ball drive mechanism in 1957 to provide greater radial torque and longer tool life.
